Tyrannosaurus

 

Tyrannosaurus Rex a very large carnivorous dinosaur who lived in the Late Cretaceous period between 66 and 97 million years ago. He was from a family of similar dinosaurs, who are know as the Tyrannosaur group (T-Rex being the largest of them all). His remains have been found as far apart as North America and Eastern Asian Countries.

Tyrannosaurus Rex

Tyrannosaurus was the largest carnivore of the whole cretaceous period, and was undoubtedly feared by most other dinosaurs at the time.

An adult Tyrannosaurus measured more than 14 metres from nose to tail. His huge skull alone was nearly 1.3-1.5 metres in length. He walked on 2 legs, which made him a 'bipod', and was as over 6 metres tall (about as high as a house).

Weighing about 8 tonnes (8,000kg - as much as 4 large cars) he was a fearsome sight to any eyes. To make him even more frightening, his sharp, pointed teeth were about 15cm long, with serrated edges (jaggedy, a little like a shark's teeth), so that they could easily tear through thick skin and flesh.

His arms were short in comparison to the rest of him, but they were very strong, and were equipped with no fingers, but 2 rounded claws, which may well have been used to grab hold of his victims, to stop them from running away. Once the claws had the prey grasped for a second or 2, the Tyrannosaurus could bite with his huge mouth and teeth, and dinner would be served.

Because his head was so large, and because tyrannosaurs normally stooped forward (especially when eating), his large and heavy tail was a necessity. It prevented him from falling over. He could have been able to use it as a weapon to hit other creatures, but probably not, since the end with the head on it was even more dangerous.

Since the bones of Tyrannosaurus are normally found near to the bones of ceratopsians (horned dinosaurs, such as Triceratops), it is presumed that these creatures were the Tyrannosaur's normal food. A Tyrannosaurus wouldn't be found behind every bush. In fact, there was only 1 in every 100 square miles (about 260 sq km).
